Hydroponic Plants
Hydroponic plants grow by taking up nutrients from a nutrient solution instead of soil. The nutrient solution contains all required macro and micronutrients. Hydroponic plants use inert media as a growing surface, e.g., Coco-Coir, Perlite, Vermiculite, etc.
Peculiarities of Hydroponic Plants
Here are some peculiarities of these hydroponic plants.
Conserves Water
They conserve water because there is no soil present in the system, like in regular farming. It saves up to 90% water as compared to traditional gardening and farming.
Nutrient Solution
Plants directly take up nutrients from a nutrient-rich water solution rather than soil.
Soilless Cultivation
Plants grow without soil and uptake their nutrients from the nutrient solution.
Fewer Pest Problems
Hydroponic systems are controlled and usually indoor. This makes it safe from pest attack.
Larger yields
Hydroponic plants have a higher cultivation rate, i.e., 30 to 50%. Due to a higher cultivation rate, they yield more.
- A reduction in pests and fungus
- Better Yield
- Crops grow faster
Expensive to set up
Hydroponic farming is more costly than traditional farming due to the higher initial cost. Moreover, it requires high maintenance.
Hydroponics reduces time
It is time-saving as compared to traditional farming.
Less space
It requires less space as you can grow them in vertical farming.
Problems affect plants quickly
Hydroponic plants are vulnerable to disease attack. If any problem occurs, the entire setup becomes compromised.

Hydroponic Plants Grow Out of the Tank
Here are some plants that you can grow in your tank as hydroponic plants.
Pothos
It is a vine plant with beautiful heart-shaped leaves. Aquarists love it because it is hardy and can go with hydroponic systems. It shows optimal growth at low light and does the best job of removing nitrates from the tank.
Moreover, it serves as a decoration. You can train the vine branches and create your desired backdrop with its beautiful leaves. It has a stringy root system that creates a jungle in the tank, and fish love to explore it.
Peace Lily
White flowers and glossy green leaves help to elevate the look of any tank. You can achieve this elevated look with a Peace Lily. It does well in low light and higher humidity. Moreover, it acts as an air purifier, efficiently absorbs nutrients, and participates in nutrient cycling.
Lucky Bamboo
It is not an actual bamboo, but it sounds like a bamboo due to vertical growth. Lucky bamboo adds an elegant vertical element to the tank. It is a popular choice due to its slow growth. Moreover, it grows in such a way that leaves leave the water surface, and roots submerge in the water. Moreover, in some asian societies, it is considered a sign of good luck in the houses.
Spider Plant
It is suitable for hydroponic systems due to its adaptability and air-purifying characteristics. Their offshoots grow on the stalk, and you can propagate them easily. If you grow them in the tank, they will provide shelter to the fish. Give them a moderate light and enjoy the beauty as they adapt to various situations.
Philodendron
Whether you like the horizontal or vertical decor, you can grow philodendron in your hydroponic system. If you love horizontal growth, go with velvet leaf, and otherwise, heart leaves will serve your purpose. They absorb nitrates, nitrites, and ammonia from the water and make the tank toxin-free. However, ensure that leaves don’t touch the water as they contain mild toxins.

Sweet potato
Sweet potato is another hydroponic plant. It shows faster growth. It can reach up to 3 feet high within one month. They require frequent trimming to avoid overgrowth. Other than commercial use, they help in decoration with heart-shaped leaves. They have an extensive root system that helps in nutrient absorption.
Basil
Basil is another hydroponic plant with an excellent growth rate and has a high market demand. It is an edible herb. Under moderate to higher light and warm water conditions, it shows a fast growth rate. You can grow it in a fish tank, as it can help to clean the water.
Mint
With benefits and beauty, Mint is another hydroponic plant whose leaves emerge above the water surface. It requires minimal maintenance, except pruning. Regular pruning helps to keep its growth under control.
Aglaonema
It is another popular hydroponic plant. It shows robust growth and has an air-purifying quality that improves the indoor air quality. It shows optimal growth at ambient light, and roots completely submerge.
Wandering Jew
A wine-like branch and multi-colored leaves plant is a favorite of everyone to grow in the house. You can enjoy this beauty with wandering jew by growing it in your hydroponic system. It requires regular pruning as its vines can grow very long. Its roots provide a bed for the fish to take a rest near the water surface.

Optimise Water Condition
Each plant and fish has their own water requirements. However, here are parameters for recommended fish and plants to thrive in the tank.
| Parameter | Value |
| pH | 6.8 to 7.2 |
| Temprature | 72 to 82°F |
| Ammonia | 0 ppm |
| Nitrite | 0 ppm |
| Lighting | 10 to 12 hours |
| Weekly water change | 20 to 30% |
Plantation
- Rinse the roots.
- Put them into net pots with growth media.
- Put the pots or plants into water in such a way that the leaves remain out of the water.
- Use air stonesfor optimal aeration in the tank.
- Leave them and be patient. Don’t panic over initial wilting.
